You can't and shouldn't.

Like I've just posted on netnews in response to your first query, if
you want to use malloc (or more generally libc) with multiple threads,
the application (in your case the perl interpreter) will have to be
linked against libpthread.

Loading libpthread at runtime cannot work properly, AFAIK.
